FLOOR PLANER.

i Application led December 21, 1920. Serial No. 432,216. n

To all whom t may conce/m:

Be it known that I, RALPH L. CONNER, a citizen of the United States, residing at Wilmington, inthe county of New Castle and .State of Delaware, have invented certain new and useful Improvements in Floor Planers, of which the following is a specification. f l

One object of my invention is to provide an improved floor planer which can be easily pushed and pulled across a floor and which will include a motor driven cutter operative to effectively plane the Hoor.

Another object is to provide improved means on the planer of my presentvinvention which will sand paper the floor, by power derived from the motor, after the cutter has operated; said means being ,adjustable to sand paper the overlapping portions which have been cut by the cutter.

A further object is to provide improved means for lifting the cutter out of engagement with the oor at the will of the operator.

These objects, and other advantageous ends which will be described hereinafter, l attain in the following manner, reference be ing had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved planer, f

Figure 2A's a sectional plan view taken on the line 2-2 of Figure 1,

` Figure 3 is a sectional elevation taken on the line 3 3 of Figure 2,

Figure 4 is a sectional plan view taken on the line 4 4 of Figure 3 through the parting of the frame, and

Figure 5 is a fragmentary side elevation showing the sand papered device having been moved to operate upon the floor.

Referring to the drawings, 6 represents a main frame which includes an upper section 7 and a lower section 8, both of which are preferably made of metal.l The upper section 7 includes two side rails 9 and 10 lwhich, are spaced apart. longitudinally as clearly shown in Figurey 2. These side rails at their forward ends have depending eX- tensions 11 which have a transversely ex- Y tending beam 12 connecting them. at their bottoms; said .beam including two lon gitudinally extending slots 13. rlhe lower surface of the extensions 11 and, beam' 12 slant upwardly toward. the rear and a gage` plateor' shoe 14 is held in engagement with they lower surface of thev beam y12 by means ofscrews or bolts 15 which extend' through the slots 13; said screws or boltshaving heads of larger width than the widths of the slots andrearwardly; the lbottom surface of the gage plate or shoe 14 being normally horizontal so that the gage plate tapers forwardly asL clearly shown in Figures l and 3.

secured to the lower surfaces of the side rails 9 and 10 by screws 16al so that `a parting 16 is formed between the sections 7 and 8; This parting may be machined so as to provide a close and accurate fit and bearingsi17 are provided jointly by the upper and lowersections at the line of parting; said bearings serving for the journals ofa cutter shaft 18 which has a pulley 19 on one end which is driven by a belt 2O *from the pulley 21 of an electric motor 22 which is secured to the top ,pushedby a handle 27; said handle at its -lower end being secured by the bolts which secure the rearY of the motor to the frame. A floor-engaging roller 28 is positioned within the frame and has trunnions'29which have bearings in a bracket 30; said bracket being pivot-ally mounted forward of the roller on bolts 31. The bracket 30`includes upwardly extending arms 32 between which extends av bar 33.y One 'end 34 offa bell crank lever 35, which is pivoted to the handle 27 is adapted to engage against the bar` .100

33 when the bell kcrank lever 35 is swung on its pivot and ly provide for thispurposaa link 36 whichs connected to the other armk 37 o f the bell crank `lever 35:said link 36 .being adjustably connected to the handle 27 and. having Van adjusting screw 38 which can so that the shoe can be adjusted forwardly The lower `section'8 of the main frame is be moved by the workman so aste force the y portion 34 bf the bell crank lever 35'=in fengagement with the bar 33 ofthe bracket-30,

and. thereby yinove` the` roller 28: ldownsinto engageinentwith the floor and tilt ,the entire planer on the gage shoe 14 as a fulcrurn and raise or lower the cut-ter 25 so that its blades will cut any desired depth. 'This adjusting screw 38 tits a tapped hole 38aA in a meniber 27a which is secured to the handle 27 so that by turning,` the adjusting screw, the link will be moved as above set forth for the pur-pose ot varying the depth of cut of the cuttingl blades. y n

It will be understood that the depth ot cut may be further regulated by moving the rage plate or shoe 14 forwardly or rearwardly to relatively raise or lower vthe cutter with .respect to the floor. This can be done by loosening the bolts or screws 15 and sliding the shoe 14 either :forwardly or rearwardly.

An auxiliary 'traine 39 has portions pivotally mounted on a rod 40; said rod extendingthrough slots 41 in the main trarne -6 adjacent Ithe parting 16; said rod having a bearing inside brackets 42 which have angular lendsflthrough which adjusting screws 44 extend; said adjustinT screws fitting tapped openings .45 in the rear end ot the main traine as clearly shown in Figure4; 'tightening' screws 46 being provided which extend through lateral slots 47 in the brackets 42 so that atterthe adjustment has been made by the screws 44, the brackets may be secured inrigid position. The auxiliary traine at its rear end-supports al shaft 48 upon which yis mounted an abrasive roller such as a sand paper roller 49. The arrangenient is such that the sand paper roller 49 can be inoved transversely along the shaft 48 and secured in positions overlapping the path cut by the cutter.

To Iaccomplish this purpose, I slidably key thesantl paper roller 49 to the `shaft 48 by providing a spline 50 in the shaft 48 and supplying a key 51 (see Figure 3) so that the sand paper roller will'be rotatably locked to the shaft 48. l' ylock the sand paper roller in various longitudinal positions on the shaft 49 by means oi a latch 52 which is slidahly secured toene end ot the roller 49 by screw 53 which extends through aslot 54 in the latch and Ifits a tapped hole 55 in the end ot the roller 49. The latch has a portion 56 adapted to be projected into any 'ot a series of notches 57 in the sha'tt 48 so thattheroller 49 can be secured in any ot its adjusted positions at eithersideot the path cutby the cutter 25. as clearly indica-ted by the full and dotand-dash lines in Figure 4.

The auxiliary frame 39 is supported in its raised position by springs 58 which bear on fthe under part ot the auxiliary traine l'and"which have portions which ytit within cavities 59 iii"theffloi'ver trarne `section 8 as 'elearlyshownin Figures 'l and. Vlheauxlify'tifarh 89has extensions @Owhichftorin a mounting for a bar 61 adapted to be engaged by an arm 62 of a bell. crank lever 63; said bell crank lever 63 being4 p'ivoted to the handle 27. rlhe arm 64 of the b'ell crank lever 63 is connected by a link 65 which is yslidably mounted a ljacent the handle 2T and at its upper end has a loop 66 which can be pulled by the workman to swing thc lever G3 and cause the arin 62 to swingr the auxiliary traine 39 downwardly against the action of the springs 58 and thereby move thegsand paper yroller 49-into enga-gement with the Hoor.A The shaft 48 has-a pulley 67 thereon which is drivenbya belt (i8 troni a pulley 69 on the end of the sha'tt `18 opposite the pulley 19. Thus the shaft 48 and sandpaper roller 49 are driven 'troni thc motor through the medium ot the shaft i8.

Inoperaiion the `planer can be nioved across the door tor `the cutting action and during this action the planer rests on the shoe 14 and roller 28; the of cut being regulated by the adjusting screw 88 or the shoe y14. lf it is necessary during this action or during' the rearward movement ot the planer to disengag'e the cutter trono the oor` the same can be lc one bythe workinan merely4 `liftingr slightly on the handle 27 androcking the planer on the gage shoe 14 as a Julcrurn and l' preferably provi e the shoe 14 with a forwardsrnoothrounded edge .14? to y-perinit this action without juring the floor, or theworkin an to disengage the cutter from the 'loor can rock the planer in an opposite .direction and `in order to provide against aiiyjpo'ssibility of injuring the floor it `this 'latter iiiovernnt is resorted to, I roundv the rearcoriiers .8a of the lower traine section 8 as K clearly shown in Figure 1. papering device the cuttercan be iii-st inoved into an inoperative position relatively to the ioor by operating the adjusting :screw and `then the workman can niove (thegliiik l.lVhen using `the sand 35 to swing the sand .paper roller 49d'own into 'engagement with `the floor as above specified; l j 7 j y i i It it will be noted that it tbe` belt A68 hecomes slack by `use that this slack can be taken up `by loosening the bolts 46 `and turning the adju stin g screws 44. Iii this manner `the auxiliary tranne l39 `can be ,nioy'ed rearwardly zto `take up r'tor .the slack oi" the belt y65% `.atter which the screws 46 can be again vtigrlgltened and hold the `parts intheir ad- Having thus described my invention, what I claim as new and desire to secure by` Letters Patent is 1. A planer of the character described including a cutterhaving knives for initially planing a floor; anabrasive device optionally movable into engagement with the Hoor; and adjustable means for transversely moving said abrasive device in a plane approXimately parallel with the floor and relatively to the cutter whereby the abrasive device can overlap to various extents the portion of the floor planed by the cutter; substan tially as described.

2. A planer of lthe character described including a main frame; a ydrive shaft rotatably i mounted in said main frame; brackets connected to said main frame and adjustable toward and from said niain shaft;

an auxiliary frame `pivotally supported on said brackets; a surface removing device supported on said auxiliary frame; means for moving said auxiliary frame in either direction on its pivotal support; and means,

for rotatably connecting saidy shaft with the surface removing device whereby vthc latter will be actuated; substantially as de-` scribed; f l

3. A planer'of the character described including a main frame; a cutter rotatably mounted therein; means carried by said.

it can ybe'moved in the direction of the width of the path cut by said cutter;`and

means ttor locking said abrasiverollerto its shaft in various adjusted positions; substantially as described. t

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
